Final answer:
The instruction that guides computer network incident responses can vary but commonly follows ITIL guidelines or an organization's SOPs. In some contexts, like the U.S. Navy, it could be the OPNAVINST.
Explanation:
The instruction that governs all computer network incident responses is typically detailed in an organization's Information Technology Infrastructure Library (ITIL) guidelines or in standard operating procedures (SOP) specific to an organization. In the context of the U.S. Navy, the relevant instruction could be the Office of the Chief of Naval Operations Instruction, known as OPNAVINST. The correct choice depends on the specific context in which the policy is being applied or the organization in question.
